ROTARY ENGINE.

Specification of Letters Patent.

Patented July 22, 1913.

Application filed June 28, 1912. Serial No. 706,473:

To all whom it may concern:

Be it known that I, NORMAN J. om, a subject of the King of Great Britain, residing at Mont Nebo, in. the Province of Saskatchewan and Dominion of Canada, have invented new and useful Improvements in Rotary Engines, of which the following is a specification.

The invention relates to engines, and more particularly to the class of rotary engines.

The primary object of the invention is the provision of an engine in which the direction of rotation of the piston may be easily and quickly reversed, without necessitating the changing of its parts, or the stopping thereof, and obviating the use of the valve chest ordinarily employed in engines.

Another object of the invention is the provision of a rotary engine of this character which is simple in construction, capable of operation in an efiicient manner in reverse directions continuously, without loss of speed, and that may be manufactured at a minimum expense.

Other objects of the invention will be in part obvious, and in part hereinafter set forth.

The invention accordingly consists in the features of construction, combination of elements, and arrangement of parts, as will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the following claims.

In the drawings: Figure 1 is a vertical longitudinal sectional view through the engine. Fig. 2 is a sectional view on the line 33 of Fig. 1. Fig. 3 is an end elevation.

Similar reference characters indicate cor responding parts throughout the several views of the drawings.

Referring to the drawings by numerals, the engine comprises a suitable base 5, from which rises a vertical cylindrical casing 6, the ends of the casing 6 being closed by removable heads 7, and at one side of the casing is provided an enlargement 8 formed with an elongated opening 9, in which is mounted a reversible abutment, presently described.

Journaled centrally in the heads 7 and passed transversely through the casing is a rotatable shaft 10 supporting a circularshaped piston 11 which is keyed or otherwise secured to the shaft, the piston being formed at diametrically opposite points with recesses 12, communicating with slots 13 extending longltudmally 111 the piston 11, and in which work wings 14, the same being formed at their inner edges with guide a heads 15 provided with spaced apertures 16, through which are passed guide posts 17 suitably fixed within the recesses 12 in the piston.

Surrounding the guide posts 17 are coiled expansion springs 18, the same being designed to act upon the guide heads 15 for sustaining the wings l4: projected from the piston and in contact with the inner surface of the casing, during the rotation of the piston.

Disposed within the opening 9 is a re versible abutment, comprising a block 19, the same being supported upon a pivot 20 suitably journaled in the side walls of the opening 9, and this abutment is adapted to be moved so as to alternately bring one end or the other thereof into projected posit-ion interiorly of the casing 6, so as to form a cam face 21, against which is adapted to frictionally contact the wings 14, during the rotation of the piston, whereby the driving fluid will act upon the wings 14 for the to tation of the piston.

Formed in the block 19 and extending through opposite ends thereof are branch inlet and exhaust ducts 22 and 23, respectively, the branch inlet ducts 23 opening through opposite ends of the said block, while the exhaust ducts open through the inner face thereof, both the inlet and exhaust ducts being disposed in diverging relation to each other and communicate with inlet and exhaust pipes 24 and 25, respectively. Formed on the outer face of the block 19 is an car 26, to which is connected a reversing arm 27, which may be manually operated for reversing the abutment block 19, thereby altering or reversing the direction of movement of the piston within the casing, as will be clearly obvious.

In the operation of the rotary engine, the steam or other driving fluid enters from the inlet pipe 24 through the inlet duct 22 and presses on one end of the abutment block 19 in the casing, and on one side of one of the wings 14, adjacent thereto. This pressure upon the wing 14: causes the piston to rotate, the steam or other driving fluid 011 the other side of the wing 14 being discharged through the exhaust duct 23 and exhaust pipe 21 to the atmosphere. It will be clearly obvious that the abutment block 19 may be reversed forchanging the direction of travel of the piston.

From the foregoing, taken in connection with the accompanying drawings, it is thought that the construction and operation of the invention will be readily understood, without requiring a more extended explanation, and therefore the same has been. omitted.

hat is claimed is 1-. The combination with, a cylinder having a pocket in one side, a, rocking abutment mounted within the pocket, a rotor arranged within the cylinder and having a displaceable wing adapted to be operated upon by the rocking abutment, the said abutment being-ofa size to close the pocket when eitherend thereofis projected into the cylinder, means connected with the abutment for ac tuatingthe same, the said abutment beingformed with a plurality ofintake and exhaust passages, one of said passages opening through opposite ends of the abutment and the other passage opening through the innermost face thereofnear its end.

2. The combination with a cylinder having a pocket in one side, a, rocking abutment mounted Within the pocket, a rotor arranged; within the cylinder and having a displaceab-le wing adapted to be operated upon by the rocking abutment, the said abutment being of a size to close the pocket when either end thereof is projected into the cylinder, means connected with the abutment for actuating the same, the said abutment being formed with a plurality of intake and exhaust passages, one of said passages opening through opposite ends of the abutment, and the other passage opening through the innermost face thereof near its end, and fluid supply and exhaust pipes communicating with the said passages medially thereof and at the side of the abutment.

In testimony whereofI aiiiX my signature in presence of two Witnesses.
